Why does Dell monitor show a lock icon: 2 ways to fix it

You can lock your screen to get additional privacy. Once you hit the Lock button, no one can see what happens on your screen until someone unlocks the display. But how to do it? You have two options on how to remove the Dell monitor lock icon.

Method 1: press the MENU button

It is the fastest way to get rid of the dell monitor lock symbol

  1. Hold the MENU physical switch for 10-20 seconds until you see that screen is unlocked.
  2. Release the button and wait for approximately 10 seconds.
  3. Press any other button to test a monitor menu.

From now on you can use the display as you wish. It will be working just fine. If you want to lock the computer monitor, hold the MENU for a minute and release the button once you see a lock icon.

Method 2: make a cold reset

Reset Dell display

Sometimes, a previous method refuses to work as it should. It often happens when the monitor menu button is not working. In this case, try a cold reset to remove the Dell monitor lock symbol. Power down the monitor and unplug all cords from it, including power. You can use a screwdriver to loosen the screw connection. It will ease the unplugging process on a Dell monitor screen.

Once you do this, hold the POWER (far right button) button for approximately 7-10 seconds. It discharges the remaining current in the monitor. Release the finger and press POWER once. Now you can start to reconnect cables one by one.
